According to the filmmakers, ninety percent of Mark Wahlberg's stunts in the film were done by him.

For the first time, Optimus Prime speaks in his native Cybertronian.

T.J. Miller reportedly did not get along well with director Michael Bay during the course of filming. Miller compared it to a "very bipolar experience" working with Bay, who once told Miller on set, "Nothing that you've said is funny, T.J.! Not one thing all day! We hired you to be funny! There's three hundred people here! None of them are laughing at you! Say something funny! I can still cut you out of the movie!"

Originally, director Michael Bay was not going to direct a fourth Transformers movie, but he had an experience that changed his mind. After Transformers: Dark of the Moon (2011), Bay finally got to visit the Transformers ride at Universal Studios. Upon seeing fans waiting three blocks for the attraction, he realized he was not ready to give up the franchise just yet.

Seventy minutes of the entire movie are dedicated to action sequences.

During filming in Hong Kong, there were hundreds of onlookers watching from nearby buildings and parking garages. After filming a huge explosive scene, director Michael Bay used his megaphone to address people watching from on top of a building across the way, saying, "You guys think you're going to wait up there and be in my movie? You're gonna get digitally erased!"

Dwayne Johnson was offered the role of Cade Yeager, but he declined, due to scheduling conflicts with Hercules (2014).

Mark Wahlberg asked that his children, Ella Rae, Michael Robert, Brendan Joseph and Grace Margaret, receive roles in this film since they were Transformers fans.

Bumblebee's alternate mode in this film is a 1967 Chevrolet Camaro SS automobile for some of the film, then later a 2014 Chevrolet Camaro concept. Bumblebee also features a new burly design, sporting horns instead of antenna.

Optimus Prime's alternate mode in this film is a cabover Peterbilt, and later a customized Western Star 4900 SB truck. The cabover truck is an homage to Optimus Prime's original alternate mode in The Transformers (1984), and the tanker truck pays homage to Prime's G2 mode (where he was a 1995 Western Star 4964EX tanker truck) and Transformers Prime (2010) mode (before he took on the alternate mode of a military truck).

Director Michael Bay described Hound as "a ballerina with guns." This quote became part of Hound's dialogue.

Canonically, Autobots have blue (optics) eyes and Decepticons have red optics. In this movie, Lockdown and Stinger have green optics, and amongst the Dinobots, Scorn and Strafe have blue optics, Grimlock and Slug have red optics, and Slash has green optics.

This film was part of a deal that director Michael Bay agreed with Paramount in exchange for financing Pain & Gain (2013).

A gigantic Hong Kong set was constructed in downtown Detroit. The set was so big, that the Detroit People Mover track ended up becoming part of the set, and shooting had to be adjusted to allow the track to move through the set.

Original designs for Grimlock, the dinobot shaped like a Tyrannosaur, gave him three claws on his forearms. This was because until 1989, intact forearms of the Tyrannosaurus Rex had not been found, and paleontologists thought Tyrannosaurs had three. The discovery proved that Tyrannosaurs in fact had two claws. Grimlock in this movie is featured with the anatomically-correct two claws.

Michael Bay describes Lockdown as the film's most interesting character: "He travels the galaxy, he works for somebody else. He's here for one person, one alien, and then he's out of here; so he doesn't really want to take sides. The cause and balance of the galaxy is kind of messed up when different species play with different species, and that opens up a whole other gigantic world for Transformers."

Part of the Yeagers' getaway was shot at the Illnois Railway Museum. While there, Michael Bay took the cast and crew on a train ride, and Mark Wahlberg made a donation of forty thousand dollars to the Museum. Bay also purchased an old 1930's crane from the museum, which had "Bay City" embossed on it. He was going to have it restored and put it in his yard at his ranch in Montana.

The was the first Transformers movie not to receive any Academy Award nominations. The previous installments all had nominations in the technical categories.

Crosshairs (John DiMaggio) refers to humans as "meatbags." This is a tribute to Futurama (1999) where DiMaggio had voiced the robot Bender, who also refers to humans as "meatbags."

This is the first Transformers live-action movie where Optimus Prime does not provide an opening prologue.

Drift's original alternate mode was a Nissan Silvia S15 sportscar, but this was revised to a Bugatti Veyron Grand Sport Vitesse sportscar and a helicopter (based on the Autobot Springer, a Triple-Changer Transformer who switches between a car and helicopter). He also bears black samurai armor, in an homage to the Transformers: Animated (2007) Autobot Yoketron, another Japanese-cultured Transformer, who possessed a similar armor.

While filming in Hong Kong, Michael Bay was a victim of an extortion incident, where he nearly got assaulted by a man wielding an air-conditioner unit. On October 17, 2013, the Mak brothers barreled into the Quarry Bay set, with the younger Mak demanding a thirteen thousand dollar (one hundred thousand Hong Kong) payment from Bay, having accosted several other crew members. When he refused, the elder Mak swung the unit at Bay, which he managed to duck and wrestle away from the man. Several police officers were injured in the scuffle, with the brothers arrested. Less than a week later in Kowloon, four men extorted a production member who was setting up on the roof of a building demanding payment. One was captured, while three escaped in what was suspected to be members of a triad gang.

The film introduced a less complex, smoother design for the robots, inspired by the designs from the IDW Transformer comics and Transformers Prime (2010). Director Michael Bay compared the redesign to Batman getting a new suit in each movie.

The first feature film to be partially shot with the IMAX 3-D digital camera. Originally, only select sequences of the film were to be shot using the camera. However, once he began using it on the set, Michael Bay enjoyed using the camera so much, he not only shot up to sixty percent of the film in the format, but he had the IMAX corporation build him a second camera.

Michael Bay had resisted including the Dinobots in previous installments, as the writers had not come up with a convincing in-story reason for why giant robots, who (according to the first few installments) seek to maintain a low profile by disguising as everyday vehicles and appliances, would take the metallic form of giant reptiles who went extinct eons ago.

This is the longest installment in the franchise, at 2 hours 45 minutes.

Despite a slew of paleontological inaccuracies, this is the first major production to correctly feature the primitive ceratopsian Psittacosaurus with quills on its back and tail. Modern findings show that even more developed forms, like the famous Triceratops, might also have been covered in porcupine-like quills or feathers.

This is the first film that doesn't have a Linkin Park soundtrack, with Imagine Dragons composing a song for the film. Linkin Park would instead compose a song for the tie-in video game Transformers: Rise of the Dark Spark (2014).

Roland Emmerich, Joe Johnston, Jon Turteltaub, Stephen Sommers, Louis Leterrier, and David Yates were considered to replace Michael Bay before he decided to return for the fourth film.

Lockdown's original alternate mode in Transformers: Animated (2007) was a customized muscle car, but this was revised to a Lamborghini Aventador LP700-4.

The KSI building in the movie is actually the Blue Cross Blue Shield of Illinois building in Chicago. It is the headquarters of Health Care Service Corporation. Scenes were shot both on the exterior and interior of the building.

Many of the actors have starred in live-action adaptations: This is John Goodman's fourth live-action adaptation of a cartoon series, after The Flintstones (1994), The Adventures of Rocky & Bullwinkle (2000), and Speed Racer (2008). This is Nicola Peltz's second live-action adaptation of a cartoon series, after The Last Airbender (2010). This is T.J. Miller's second live-action adaptation of a cartoon series, after Yogi Bear (2010). This is Stanley Tucci's first live-action adaptation of a cartoon feature, he would later star in Beauty and the Beast (2017).

The Decepticon Stinger, who transforms into a 2013 Pagani Huayra automobile, is based on the Transformers: Animated (2007) Decepticon Wasp, who was an evil counterpart to Bumblebee.

When Joshua Joyce is on the rooftop in Hong Kong, you will notice that he is drinking some Shuhua milk, the same milk that Jerry Wang was drinking in Transformers: Dark of the Moon (2011).

Originally, three more Dinobots were to appear in the film, but were cut from the finished script; the apatosaurus Slog, the velociraptor Slash, and the stegosaurus Snarl. However, toys of them were still released as part of the film's toyline.

One of Bumblebee's sound bites is "I'm calmer than you." taken from The Big Lebowski (1998). The quote is spoken by John Goodman's character, Walter Sobchak. That film also starred John Turturro (Agent Simmons in the previous films and Transformers: The Last Knight (2017)) and Peter Stormare (Prometheus Black in Transformers: Animated (2007)).

The transformation sound from The Transformers (1984) is heard when Optimus Prime changes alternate modes.

Ratchet appears to have already known Lockdown prior to the movie's events. This could be a reference to the online Cyber Missions episodes, which took place between Transformers (2007) and Transformers: Revenge of the Fallen (2009), and featured Ratchet and Lockdown fighting against each other (itself an homage to Transformers: Animated (2007)).

Hound's original alternate mode in The Transformers (1984) was a Mitsubishi J59 military utility vehicle, but this was revised to an Oshkosh Defense Medium Tactical Vehicle. His beefy design also pays homage to the Autobot Bulkhead from Transformers: Animated (2007) and Transformers Prime (2010), and his cigar-chewing military ways are a tribute to the Autobot war veteran Kup from The Transformers: The Movie (1986).

There are about 55 brands of product placements in the film.

In Boogie Nights (1997), Mark Wahlberg sang "The Touch", which came from the first "Transformers" cinematic feature The Transformers: The Movie (1986). Wahlberg joked with Michael Bay about singing and rapping for the movie's title track.

Crosshairs' original alternate mode in The Transformers (1984) was a Cybertronian off-road van-buggy kind of vehicle, but this was revised to the 2014 Chevrolet Corvette C7 Stingray.

According to Mark Weber, the Transformers Manager of Global Brand Development, the two-headed winged Dinobot was originally going to be called Swoop after the Dinobot from The Transformers (1984), on which he is based. However, he was re-named Strafe (after the Autobot Technobot) because his beast mode design was too much a departure from the original Swoop's classic Pteranodon appearance. The "Transformers" IDW comics paid tribute to this change by introducing Strafe as a character who starts out a normal vehicle-mode Transformer, but is mutated into a two-headed Dinobot.

The robot bird logo on Yeager's mailbox and the basketball-shooting robot in his shop are from an actual competition robotics team from Austin, Texas. They are FIRST Robotics Team 2468, from the Spring 2012 competition.

First live-action Transformers film not to feature Shia LaBeouf or any story line about the Witwicky family.

The role of Lucas was written with T.J. Miller in mind.

Originally, Lockdown was to carry the torn-out eyes of his victims as trophies tied to his hip.

Counting the fire-breath from the Dinobots, there are 563 explosions in this film. This almost doubles the amount of explosions from the previous installment, Transformers: Dark of the Moon (2011), which had 283.

Mark Wahlberg had to reshoot some scenes. This was problematic, since he had since dramatically lost weight for The Gambler (2014).

Drift recites a haiku, to Hound's annoyance. The haiku is an homage to Transformers: Robots in Disguise (2000)'s Sky-Byte, a Predacon who enjoyed reciting haikus and other poetry (as the show was Japanese animé, this quirk was carried over into the English dub).

Detroit has a monorail system that runs once every seven minutes and goes through this Hong Kong set. So they have had to work around that scheduled train and make sure they don't get any dirt or rocks on the tracks.

The house used in the first scenes was the same house in Secondhand Lions (2003).

Concept Artist Vitaly Bulgarov created an evil female Transformer called Widowmaker as a potential helper for Lockdown. She was considered, but finally did not appear in the film, having been replaced by the Stingers.

Shia LaBeouf did not appear in the film due to federal problems. When he went to jail, it was during the time that the movie was filming.

During filming, the filming camp had a sign that stated "E7". In the seventh episode of The Transformers (1984), Grimlock, Slag, and Sludge, were built to help the Autobots.

During filming, Michael Bay utilized the Shotover K1 platform for aerial shots in IMAX and 3-D-converted footage, for high-speed action sequences.

For all of the films, the filmmakers and screenwriters have visited Hasbro during development of the script to help build the story from the extensive mythology of the Transformers line.

Paramount Pictures entered an agreement with teaming with the Chinese film companies China Movie Channel and Jiaflix Enterprises, to enable filming in China.

Lockdown was originally envisioned with a vehicle mode closely resembling his appearance from the cartoon and comics, a modified muscle-car with a visible engine block, and his trademark black, green, and gray coloration. This was changed when the Lamborghini Aventador LP700-4 was chosen as his vehicle mode.

This is only the second time in all the live-action movies that Optimus transforms into a vehicle mode on-screen. The first was when he engaged Demolishor in Transformers: Revenge of the Fallen (2009).

There are about eighteen new robot characters in this film.

This is the first film to be released on Blu-ray encoded with a Dolby Atmos soundtrack.

In the scene where Shane and Bumblebee are in the design center with Stinger, the KSI executive that approaches and asks Shane what he touched, is actually Head of GM Global Design, Ed Welburn. His office, also the office of former GM executive Harley Earl, is used when Attinger meets with the Chief of Staff earlier in the movie.

The two evil human organizations, Cemetery Wind and KSI, are based on the terrorist group MECH from Transformers Prime (2010). KSI representing the science side of MECH, and Cemetery Wind representing the military side.

In Cade's house, is a poster for SXSW, or South by Southwest, the annual festival of music, film, and technology, in Austin, Texas.

Through the miracle of film editing, early in the film, Cade Yeager arrives in front of a store bearing the name Kincl, this store, and the other buildings on the same side of the street, are located on 2nd Street in Taylor, Texas. Cade walks across the street to the abandoned Uptown Theater, which is located in Chicago, Illinois.

In one scene, Mark Wahlberg walks past a robot launching basket balls. This robot, used in the 2012 FRC season, belongs to FIRST Robotics team #2468. FIRST Robotics is an annual competition for high schoolers around the world.

Transformers: Age of Extinction (2014) sponsor General Motors provided a myriad of shooting locations for the film. Most prominently, the KSI headquarters in the film, is, in real-life, the GM Design Center.

The characters of the Autobots in this film (the leader, a big green robot, an ex-Decepticon, a snarky hacker, and a yellow teenager) are similar to the main cast of the Maximals in Beast Wars: Transformers (1996) (Optimus Primal, Rhinox, Dinobot, Rattrap, and Cheetor) who have the same characteristics.

Ken Watanabe (Drift) was ill during filming, so Eric Bauza recorded a few of Drift's lines.

This was the highest-grossing film in Malaysia, grossing about 13.52 million dollars.

Isabelle Cornish, Margaret Qualley, and Gabriella Wilde auditioned for the role of Tessa Yeager.

The Hong Kong location allowed Bay to develop a vertical Parkour sequence that follows characters down the side of an apartment tenement.

The Detroit-based Hong Kong set took sixteen weeks to build from start to finish.

Mark Wahlberg and Stanley Tucci also worked together in The Lovely Bones (2009).

When Hound kills a Decepticon with his knife, a video game chime goes off.

The movie theater, at the beginning of the film, is the same theater, in which the most recent season of Castle (2009) took place. Fringe (2008) has an episode in this theater, the show was produced by "Transformer" writers Roberto Orci and Alex Kurtzman and starred "Transformers" voice actor Leonard Nimoy.

Among the Autobots, Hound and Crosshairs never transform on-screen. Drift transforms into helicopter mode and back on-screen, but is never seen transforming into car mode.

James Savoy (Titus Welliver) sports a tattoo, "Cora" on his forearm, in honor of his deceased sister.

T.J. Miller's nickname for his character Lucas is "Lucas the Doofus".

IDW comic writer Shane McCarthy, who created the character of Drift, dislikes the movie incarnation, accusing him of being a racist stereotype. Fans were quick to point out that McCarthy has also used words to imply he's not fond of Drift's development in later comics (with which he wasn't involved) which most feel made him a significantly better character, and that Drift's entire original persona was little other than highly stereotypical itself. Which is a moot point, because you can't stereotype an alien robot.

Mark Ryan had earlier appeared in an episode of Kelsey Grammer's hit comedy Frasier (1993).

Stinger only transforms once in the movie.

The word "transformer" is used by three humans in the film: Attinger, Joyce, and Yeager.

On the front of the bike, used in Hong Kong during a chase scene, there is clearly a Kremzeek painted on the front, which was a creature from G1 Transformers, and feature in the Transformers Devastation game as collectibles.

Crosshairs gives the pet name "Spike" to the Dinobot Scorn. Spike Witwicky was the Autobots' human ally.

The GM design center stood for the CIA office, and the director's office is the legendary car designer Harley Earl's office. All furniture in the office was designed by Earl himself.

The stunt team trained the young stars for four weeks back in Los Angeles before the shoot. The training involved boxing, sprints, cross training, and was important, because they built a relationship with the stunt guys.

Michael Bay's department heads have a combined total experience of 850 years in the film industry.

Titus Welliver (Savoy) and Mark Ryan (Lockdown) have appeared on television shows produced by Michael Bay, Welliver in The Last Ship (2014), and Ryan in Black Sails (2014).

First live-action Transformers film where Megatron is voiced by Frank Welker (albeit in his new form as Galvatron).

Landon Liboiron, Luke Grimes, Luke Mitchell, Hunter Parrish, and Brenton Thwaites auditioned for the role of Shane.

Michael Bay is proud of shooting this film in IMAX 3-D, and asserts that it's far better than any post-converted movie.

Set Decorator Rosemary Brandenburg brought over three full containers from Hong Kong for this set's decorations. They also hired local Chinese traders in Detroit, to make the dressings for this set. They travelled to Hong Kong to prep for the film with Michael Bay. They have huge books of photographs everyone took in Hong Kong for reference for these sequences.

Jack Reynor was chosen after his critically acclaimed performance in What Richard Did (2012).

T.J. Miller was one of the leads in the 2008 film "Cloverfield", which had its teaser trailer premiere in front of the first "Transformers" movie in the summer of 2007. A poster for "Cloverfield" can be seen in Sam and Leo's room in 2009's "Transformers: Revenge of the Fallen".

On average, there is a different camera shot every 2.8 seconds, in comparison to Stalker (1979), which has a different camera shot about every ninety seconds.

Mark Wahlberg pulled from his real-life experience as a father, in order to further develop his character.

Observe the conversation involving the CIA Director (Charles Parnell). His head covers the final word of a sentence in a poster on the wall behind him; the sentence says "Freedom isn't free". The image comes out as: "Freedom isn't (the CIA Director)."

This was Shiming Zou's feature film debut.

Highest grossing film of 2014.

Producers Lorenzo di Bonaventura and Ian Bryce split responsibilities: Lorenzo worked more in the development of the script, and Ian dealt more with the logistics of filming.

Mark Wahlberg and Patrick Winslow appeared in Pain & Gain (2013).

This film features both Reno Wilson (voice of Brain) and Cleo King (the realtor). The pair also appears together in Mike and Molly as grandmother and grandson. Mike and Molly, like Transformers : Age of Extinction, is also set in Chicago.

There's a sequence in Iceland that was shot on film.

Kelsey Grammer and T.J. Miller are part of the X-Men film franchise: Grammar played Hank McCoy in two films (and had turned down one X-Men film to appear in this one), and Miller is the sidekick of Deadpool (2016). They are the second and third cast members from the X-Men films to appear in a Transformers feature. The first was Ty Olsson, who played Mitchell Laurio in X2: X-Men United (2003), and also played played Downshift in Transformers: Energon (2004).

Cade Yeager (Mark Wahlberg) makes fun of a brother named Jerry. In Four Brothers (2005), Wahlberg's character has a brother named Jerry.

The alien gun/sword that Cade finds and uses is similar in design and function to Ka D'Argo's Qualta Blade, which opens to reveal a pulse rifle in the Farscape (1999) franchise.

In the credits, Bingbing Li is listed as Li Bingbing and Bingbing Li.

Michael Bay: the driver of the truck that Bumblebee and Optimus destroy after they jump over bridge during Galvatron's attack.

According to the producers, the Dinobots weren't going to appear in the film, and would appear in the fifth film instead. But because Hasbro and the producers pressured Bay, he eventually decided to put them into the end of the film, so they can be introduced, and have a bigger role in the next film.

Galvatron is based on his original version from The Transformers: The Movie (1986) (Megatron resurrected as a minion, who eventually rebels and returns to leading the Decepticons), and Nemesis Prime from Transformers Prime (2010) (a human-built duplicate of Optimus Prime). His black color scheme is also an homage to the The Transformers (1984) Decepticon Motormaster, an Earth-built clone/rival of Optimus Prime.

At the end of the film, Optimus Prime leaves Earth to embark on a quest to find the creators of the Transformers. This was one of the originally proposed ideas for the plot of The Transformers: The Movie (1986) that was rejected for unknown reasons.

Almost all the marketing showed only the Dinobots. However, they show up for only fifteen minutes of screentime.

Harold Attinger is the first human being Optimus Prime has ever killed in any movie.

A scene was shot where Attinger kills a Chinese citizen to steal his car. This scene was removed from the film, due to objections from the Chinese government.

According to Michael Bay, Lockdown's Knight ship plays a major role in the film and its sequels: "The ship has a lot of meaning and backstory that can go into other movies."

This is the first film in the franchise in which none of Autobots are killed during the battle scenes. Only Ratchet is killed early on when being hunted by the humans, and Leadfoot is discovered to have died before the beginning of the film's story.

Bumblebee is the only original Autobot from the first movie to not have died. (Optimus died and later resurrected in Transformers: Revenge of the Fallen (2009))

Lockdown's facial features resemble those of the Quintessons, the god-like biomechanical creators of The Transformers (1984). This hints at the Quintessons being Lockdown's masters and their appearance in a sequel.

The two main villains, Lockdown and Galvatron, never meet face to face.

The film contains tributes to Transformers: Animated (2007): The film is set in a future era (2015, four years after Transformers: Dark of the Moon (2011)). Ratchet and Lockdown know each other. Megatron's head is online in an industrial complex, and he uses human technology to reform himself. Lockdown, the Dinobots, a Japanese-styled Transformer (Drift, Yoketron), and a Bumblebee clone (Wasp, Stinger) appear. Inventor Cade Yeager is based on Dr. Isaac Sumdac (both are single parents with daughters). Joshua Joyce is based on industrialist Porter C. Powell (both have large glasses and end up creating Decepticons).

The KSI storyline of building man-made Transformers is similar, though probably unintended, to the controversial "Transformers: Kiss Players" series, where an agency formed a anti-Transformer army from the components of Decepticons and ended up reviving the Decepticons.

During the end scene, where Cade is hugging Tessa, you can obviously tell that they are in Chicago, not Hong Kong.

Shia Labeouf declined to reprise his role as Sam Witwicky in this film

The film draws inspiration from the Transformers IDW comics: The Transformers on Earth are being hunted down in the aftermath of a devastating battle. Attinger's plan of getting a government contract through man-made Transformers was taken from the Machination story arc (the Machination forms Transformers for profiteering). A human operative justifies his actions as necessary for protecting mankind, said actions include working with evil robots (in the comics, it was Spike Witwicky, in the film, it's Attinger). The heads of Ratchet, Sentinel Prime, and Megatron in a laboratory pays homage to Sunstreaker's head being kept in a Machination lab. Drift makes an appearance. The Dinobots appear as a separate faction, who eventually join the Autobots.

The film pays homage to the "RoboCop" franchise: The story is set in a dark future. Galvatron/Megatron is rebuilt into a new body, just like Alex Murphy and Cain. Harold Attinger is based on Dick Jones (and Paul McDaggett). He orders a manhunt for the heroes, is simply acting to get a government contract, holds an alliance with a Decepticon, and near the end of the film, holds someone hostage and gets gunned down. Joshua Joyce is partly based on Dr Juliette Faxx. He builds a new Transformer, and refers to the Autobots as outdated. Savoy's death scene is similar to Jones' death (a fall from a building window). Optimus Prime acquires the ability to fly, just like RoboCop does.
